BitLocker is an encryption feature available in Ultimate and Enterprise versions of Windows 7 and Vista, but requires a Trusted Platform Module (TPM) on the system. Not all systems include TPM and today we take a look at how to bypass it so you can use BitLocker.

Enable BitLocker

You can use BitLocker to encrypt an entire fixed drive, such as the local drive Windows is installed on or an internal data drive. For removable flash or external USB drives you can use its younger brother, BitLocker To Go. First let’s take a look at how to enable BitLocker on a local hard drive.

To encrypt an entire drive, simply right-click on the drive and select Turn on BitLocker from the context menu.

Next you’ll need to choose a secure password that will be used to access the drive.

You’re prompted to store the recovery key which is used in the event you lose your password or smartcard. If you store it as a file make sure that it’s not on the same drive that you’re encrypting.

Confirm you want the drive to be encrypted then wait until the process is complete. The amount of time it takes will vary based on the size and amount of data on the drive.

To access the encrypted drive you’ll need to enter in the password to unlock it.

The drive icon will change to show it’s encrypted with BitLocker, where the gold lock indicates it’s locked up and the gray lock is displayed after you have unlocked it.

Use BitLocker on a Drive Without TPM

What happens if you get this goofy error and what is a TPM anyway? TPM stands for Trusted Platform Module which is a microchip in a computer that supports advanced security features. It’s where BitLocker stores the encryption key. If you have a drive that doesn’t have a compatible TMP then you’ll need to use the following steps and have a flash drive.

Enter in gpedit.msc in the search box of the Start menu and hit Enter.
